What is Valid Measures™

Valid Measures™ is an innovative range of mapping, impact assessment and market research tools, provided exclusively by Valid International Limited.

Our Simple Spatial Survey Method (S3M) is a wide area, high resolution mapping technique that obtains spatially representative information on a range of demographic, behavioural and public health indicators.

Our Rapid Assessment Method (RAM) was designed as a quick, simple, low cost small area survey method for producing spatially representative information on a wide range of demographic, behavioural and public health indicators.

How was Valid Measures™ developed

In collaboration with Brixton Health (a core research partner to Valid International, headed by consulting epidemiologist Mark Myatt) we developed a range of mapping and surveying tools that have the potential to transform how programme monitoring and evaluation, impact measurement and ‘base of the pyramid’ market research is undertaken in developing countries.

Why use Valid Measures™

Our tools allow survey data to be spatially disaggregated with very high granularity and presented as heat maps illustrating how particular indicators vary geographically even down to village level. Our bespoke software and approach allows results to be fed back far more quickly than traditional survey analysis and affords the possibility of real-time data checking and verification, thereby increasing the speed and reliability of the survey results

Isn’t ‘spatial’ surveying way more expensive than other methods?

We do not believe that has to be the case. Valid International has developed, trialled and implemented cost-effective spatial sampling methods that allow for the reporting of indicators at significantly finer spatial resolution than those reported by standard survey methods.  Specifically, our approach can:

  • Produce high resolution gridded and/or interpolated map surfaces of key health and nutrition indicators and their co-variates
  • Provide spatial data that will inform the creation of a geospatial model of geographical access to health and nutrition services and interventions
  • Provide insightful ecological analysis and spatio-temporal point pattern analysis to detect spatial clustering and spatial correlation of health and nutrition indicators and their co-variates and programme coverage
  • Generate evidence for change (what worked and what didn’t)
  • Enable the research results to be acted upon, through active stakeholder management and positively influencing next steps, such as policy formulation in-country.
